CHARLES DELORMEND EMILE BROCl-ION, OF TROYES, FRANCE.

, METAL RAILWAY-SLEEPER.

SPECIFICATION forming part of Letters Patent No. 429,607, dated June 10,1890.

Application led December 2, 1889. Serial l.\Tc|.332,290. (No model.)

To all whom it may concern:

Be it known that we,CHAELEs DELORME and EMILE BROCI-ION, citizens of theRepublic of France, and residents of Troyes,France, have inventedcertain new and useful Iniprovementsin or Relating to Metal Railway-Sleepers, of which the following is a specifi-V cation.

The improved metal sleeper constituting the object of this invention isrepresented in the drawings accompanying this specification, in whichdrawings- Figure 1 is an elevation, and Fig. 2 aplan, of the sleeperwith portions of rails attached. Fig. 3 is a transverse section on theline AB of Fig. l. Fig. 4 is another sectional view on the line C D ofFig. 1. Figs. 5 and 6 are perspective detail views of parts of thesleeper.

, On examining the iigures it can be seen that the metal sleeperconsists of two distinct parts, the body E and the base F; The body E isof iron or steel of 1-shaped or channeled section, the upper surface ofwhich forms the bed or seat of the rails, while the vertical webs formthe sides of the sleeper. The base F is also constructed of, preferably,rolled iron or steel, and is formed with two longitudinal parallelgrooves G G', into which fit the lower edges of the two vertical webs othe body E of the sleeper.

Beyond the grooves G G at each side of the sleeper, extends the base F,so as to form two longitudinal edges, which support the weight of therails, whereby the sleeper, when once iixed in position, will be solidlybedded and held in a vertical position.

It can be easily understood that by the webs of the body E beingretained in the grooves G G of the base F the rigidity of the body isconsiderably increased. The webs of the body E, by being so retained inthe grooves G G, cannot become spread apart or closed toward each other,while at the same time the sleeper retains sufficient elasticity.

Among the many forms of sleepers hitherto devised are some which aremadewith a view to economy; but these have been deficient in rigidity,and those which possessed sufficient resistance were of no practicalvalue, because, owing to their complicated nature and great weight, theywere too costly.

The simplicity of construction combined with the lightness of oursleepers lessens their cost to an extent not hitherto attained.

The body E of the sleeper is attached to the base F by means of rivetsor bolts l-I, which serve at the saine time to hold the clips or chairsof the rail. So constructed our sleeper is of great strength; but takingintoaccount the transverse strains which are to be met more particularlyat the curves of the track by the bolts or rivets joining the two partsof the sleeper, the body E and base Fv act to diminish that strain, andthereby afford greater security. To attain this object, we make the baseF longer on bot-h sides thanrthe body E,

as is shown in Figs. l, 2, 3, 4, and G, and we.

divide by two longitudinal cuts the said proj ectin g portion. The twosymmetric parts R include the grooves G G', andthe part S is between thetwo parts R. The two parts R are thrned up to a right angle against theends of the wings of the body E, which 'fitup to a certain point oftheir height into the upturned parts of the grooves G G. In the same waythe rivets or bolts H, and also the base F, assist with the ends Rraised against the body F. to hold the latter transversely,whereby thebolts or rivets H are to a corresponding extent relieved. The part S isbent downward to a right angle to the base in such a way as to enter theballast, and thus afford all the required anchorage to secure thesleeper in position. The edges ot' the raised parts R on both sides ofthe grooves G G also contribute to retain the sleeper in position, asthese parts are also bedded in the ballast.

Our sleeper can beused for supporting rails of any section.

At X in Figs. l, 2, and 3 we represent, as an example, a iiange-railheldupon our sleeper by means of the chair-clips or jaws I, of iron, steel,or any other suitable metal. -This chair is fixed upon the upper surfaceof the sleeper by means of the same rivets or bolts I-l as serve to jointogether the bodyE and base F of the sleeper. The flange M of the railis placed in the chair I, and is held there by a key L, which may beprovided with a hole N, into which a pin may be placed for the objectofpreventing any displacement of the key L.

As it is sometimes necessary to maintain the rail upon the sleeper bymeans of clamps, spikes, or screws, as is shown with the rail Y IOC inFigs. l and 2, we place into the empty space in the interior of thesleeper, at its ends, a block P of Wood, which we fix in position by therivets or bolts H, employed to hold together the two parts of thesleeper, and we form holesQ in the upper surface of the body E, so as toleave a passage for the woodscrews or clamps, which serve to attach therail to the sleeper. These wood-screws, spikes, or clamps fit solidlyinto the wood P and maintain in position the rail as perfectly andsatisfactorily as if Wooden sleepers Were used.

It is evident that the Vdimensions and the metal of which these sleepersconsist can be varied according to requirements, and alsodii'erently-shaped rails could be lixed upon our sleepers, and also thatthere may be used any kind of chairs or clips other than those beforedescribed for securing flanged rails in position.

Ye claiml. In a railway-sleeper, the combination, with thechannel-shaped body having the downwardly-turned sides extending' fromend to end, of the substantially fiat extended base having thelongitudinal grooves for the downwardly-extending sides of the bodyexi-ending from end to end of the ties, whereby distortion is prevented,substantially as described.

2. In a railway-sleeper, a base, such as F, longer than the body E, theparts projecting beyond the ends of the body being divided into threeparts R R S, the first two, including the prolongation of the grooves GrG', being turned up toward the ends of the webs of the body E,which websfit into the grooves G G of the said base, while the third part Sis bentdownward to a right angle to the base, in order to iit into the ballast,substantially as herein specified, and illustrated in the accompanyingdrawings.

3. In a railway-sleeper, the combination, with the body having thedownwardly-turned sides, of the base having the independent grooves forsaid sides and the extended ends bent upward and forming stops againstwhich the ends of the body abut, substantially as described.

4. In a railway-sleeper, the combination, with the channel-body andindependent base, of an internal wooden block, a chair 'for holding therail in position, and the boltor rivet passing through the chair, body,block, and base, whereby all the parts are held rigidly in position,substantially as described.

5. In a'railway-sleeper, the combination, with the channel-body andindependent base, of a wooden block fitted in said channel and betweenthe body and base, and a bolt or `rivet passing through the body, block,and

base for holding the parts rigidly in position, substantially asdescribed.

In testimony that We elailn the foregoing as our invention We havesigned our naines, in presence of two witnesses, this 14th day ofNovember, 1889.
